Objective: Solve 3y - 20 = 8y for y.
Step 1: Collect the y-terms.
To collect the y-terms, you'll need to subtract 3y from both sides.
3y - 20 - 3y = 8y - 3y
-20 = 5y
Step 2: Isolate y.
Now that there is only one variable term, you must isolate the variable by dividing the term by the coefficient of the variable.
-20 ÷ 5 = 5y ÷ 5
-4 = y
Answer:
y = -4
Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2
Answer: 0.0108
Step-by-step explanation:
Given : 
Since the alternative hypotheses is right-tailed, so the test is a right-tailed test.
Sample size : n=30
The degree of freedom for t-distribution= 
The by using the normal t-distribution table , we have
The P-value corresponds to t-statistic vale 2.43 and degree of freedom 29 , is 0.01075997 i.e. approximately 0.0108
Answer: m = 5/2
